This is a simple App. If you read the description, you will be satisfied.

Injoice is a simple barebones tool for creating invoices. It is not packed full of advanced and automatic features--nor does it claim to be. Its good for putting together basic, often one off invoices that look nice. Its a little expensive, but I like it, and as long as you read the description beforehand, you will too.
